0F SEATTLE, VIASHINGTON, A CORPORATION or WASHINGTON COIN CONTROLLED-MECHANISM Application filed January 3, 1930. Serial No. 418,334.

This invention relates to improvements in coin controlled mechanism.

It is a feature of the invention. to provide a coin chute having anentrance throat which is proportioned to admit coin or other token ofnotmore than a prescribed diameter and which does not exceed a giventhickness, the throat being shaped in a manner to prevent entrance of acoin or token that is buckled or bent. 7 A further feature of theinvention consists in means for arresting coins or tokens in theirpassage through the chute in such a manner that a plurality of suchentities can be inserted, one in superimposedrelation to the other orothers, and whereby the entities will be separately and successivelyacted upon to cause a series of vending operations for each genuinecoin, the spurious entities being acted upon to prevent a vendingoperation as a resultof the presence thereof, and irrespective of thefact that a token or genuine coin may be of a less than the prescribeddiameter.

An object of the invention is to provide means for detecting thespurious from the genuine of the entities-by gauging the thicknessthereof, the slugs to a great extent, being provided with centrallydisposed openings in each, thereby causing a registration of nothickness, while av dime or prescribed coin that is worn too thin, willalso be incapable of causing a vending operation.

It is a feature of the invention to provide means acted upon by, andsubsequent to the detection operation, for causing genuine coins of theusual thickness to be deflected into or toward a coin box, and coinsthat are too thin and also spurious entities, to be deflected in amanner to be returned to the purchaser.

One of the novel features of the invention resides in detection meansoperatively connected with mechanism for arresting vending operation, ininterdependent relation.

A further feature resides in means for discharging steel or otherspurious entities before the latter reach the detecting means.

The invention has many other features and objects which will be morefully described in connection with the accompanying drawings and whichWlll be more particularly shown in Fig. 10.

Like characters of reference designate similar parts throughout thedifferent figures of the drawings.

The device of this invention is adapted for use in connection with thevending of any type of merchandise or articles and therefore it has notbeen shown associated with any special type. I have however, generallyindicated at 1, the top of the case or casing in which the mechanism isenclosed and, in this embodiment, the place where a coin, token or likeentity will be inserted.

Throughout the claims and the specification, I will use the words entityor entities generically to coins, slugs and tokens, thereby avoidingalternativeness, repetition, and antecedent confusion.

,, An entrance or throat device is mounted 'inthe top 1, and consists ofa plate 2 having a slot 3 of a length to permit insertion of a coin ofprescribed or maximum diameter and no larger. The width of the slot 3,is proportioned to limit the insertion of an entity greater than apredetermined thickness, which, in the present instance, is a fivecentpiece or nickle. Depending from the plate 2, are lips 4 which are soclosely spaced that if an entity is bent or buckled, such entity canonly be partly inserted, as will be seen by reference to Fig. 12. Theselips terminate at 5, in very close endwise relation to the ma n vcoinchute, and in practice, these lips arenot connected near or at the endportions thereof, the latter being open. It

will beunderstood that these lips 4 will also 35 prevent insertion of anentity of less than the prescribed diameter, if the latter is buckled orbent, and such entity may also be of a reduced diameter with respect tothe prescribed diameter for which the device is designed andproportioned to work. Reference will next be made to the coin chute andthe various features of structure with which the latter is equipped.

The entrance to the coin chute is indicated at 6, closely disposed tothe terminals 5, of the lips 4, asshown in Figs. 1 and 12, so that thelips 4 will guide the inserted entity into the coin chute before suchentity has passed through or from between the lips 4, as will now beclear. This coin chute has what will be termed an entrance section 7,which is vertically disposed for gravity descent'of an entityrherethrough or therein. Said coin chute has an initial or slugdischarge section 8 which isshown disposed in offset relation to theentrance section 7, slanting'down-wardlyand laterally as shown in.se'ctiorr'9, having a final discharge end 10.

Extending laterally and diagonally down- .wardly from the dischargesection 8, is a slug section 11, having a discharge outlet 12.

,As will be seen more particularly in Figs. 13

and 14, the slug section 11, junctures with the section 8 in a manner toform a release passage 13 for what I will term magnetic entities, suchfor instance as steel slugs. A magnet 14, preferably although notnecessarily of a permanent type, is secured to a mounting 15, suitablyanchored to the coin chute. The poles 16, of said magnet extend acrossthe bottom of section 8, and as a steel or like slug rolls down thechute, it is attracted by the magnet and thereby diverted into the slugsection 11, as will now be clear. Means such as a thin non-ferrous strip17, may be disposed as shown to prevent an attracted entity fromfreezing to the poles of the magnet 14, thereby insuring its dischargedownwardlyin chute 11. Said strip 17 may be anchored'at 18.

Thus it will be seen that I have provided means acting intangibly ormagnetically for discharging that type of entity subject to This base 19is adapted to be secured in the structure in which the vending and coincontrolled mechanism are disposed. At the discharge end 10, of the coinchute, the base is cut-away or bifurcated to form substantially forkedsections 20 and 21, to be later described.

In further description of the operative section 9, of the coin chute,reference will next be made to a feature whereby all entities, whethergenuine coins of prescribed diameter or less and all slugs except thosemagnetically deflected, will be arrested, or temporarily arrested in thecoin chute section 9, for purposes of detection of their character.

In the description of this feature, reference will be made to Figs. 4,5, 7 and 8. An entity arresting means is provided which, in the presentconstruction takes the form of a member or plate 22. This is a rockingplate and preferably a floatingly mounted plate,'and means which willlater be described, is provided for imparting rocking movement to saidplate. v

Said plate 22, has a set of studs 23 spaced for arresting entities ofnormal or prescribed Ill;

and across the chute passage, as shown in Fig. 4. Y I

Said plate 22, is also provided with a set of arresting studs 25, whichin this construction, is the upper set of studs and which aresulficiently closely spaced not only to arrest an entity of prescribeddiameter but one of less than such diameter, such for instance as adime. The outer chute wall 9 is provided with openings 26 for projectionof studs into the coin chute as shown in Fig. 5. By reason of the factthat the plate 22 is floatingly mounted, I preferably taper the studs 23and 25, and

' the openings 24 and 26 are somewhat e11- larged to alfordample'clearance. It will be seen from Fig. 8, that the upper studs 25,are capable of supporting a plurality of superimposed entitiesirrespective of whether they are of the prescribed diameter, theimportance of which will be later described.

Reference will next be made to the means for floatingly mounting theplate 22.

At its upper corners, the plate 22 is cut away as shown at 27 andguiding pins 28, mounted on wall 9 of the coin chute, extend outwardlythrough such cut away portions 27, and serve as a guiding means forrocking movement of the upper portion of plate 22.

The lower corners are shown cut away or interrupted at 29 and a bail 30extends across the lower margin of said plate and the ends of said bail,as indicated at 31, in Fig, 8, extend inwardly and form guiding studs orpins for coaction with the cutaway portions 29. The guiding pins 31 areanchored to the wall 9 of the coin chute. As the lower portion of plate22 is not the actuated portion, it'is advantageous to employ a bail sothat the bightof the latter will prevent the lower portion of the plate22from moving outwardly too far.

Means such for instance as springs 32, an'- chored at 33, to the coinchute and "having their free ends 34 bearing against the plate 22,normally serve to urge theplate toward the coin chute, and the thrustexercised by said springs is near the horizontal center of the plate 22.

Reference will next be made to the means employed for imparting rockingmovement 'to plate 22.

WVhat I will term a master cam, to be later described in full, isindicated at 35, and is rigidly mounted on a cam shaft 36, which latteris a main operating shaft. This shaft 7 is rotary, carries an actuatingand releasing cam stud 39. An actuating lever 40, is pivoted at 41, tothe base 19, in the rear of cam 35, and is provided with an actuatingare 42 struck from a center radius greatly reslidably engages the slot48, of an actuating or rocking arm 49, that is rigidly secured to theupper portion of plate 22, as will be clearly seen by reference to Figs.1 and 4.

Reference will next be made to a novel means for detecting the characterof entity that is arrested by plate 22.

A lever 50, which I will term a detecting lever, is hinged to the base19 at 51, to swing in a substantially horizontal plane about asubstantially vertical axis. A spring 52, normally urges said lever 50,toward the coin chute. Extending transversely through said lever 50, isa coin detecting stud 53, more clearly shown in Fig. 9. Thus stud 53,may be advantageously in threaded engagement with said lever 50, and alock nut 54, provides means for securing the stud 53 in adjustedpositions. The plate 22, is provided with an opening55, through whichsaid stud 53 freely extends, and an opening 56, in the wall 9 of thecoin chute, permits the stud 53 to extend into the latter, and intoengagement with an en ity that has been arrested by studs 23, of plate22, for purposes of detection.

The free end 57 of said lever 50, is provided with a slotted or lostmotion connection with one arm 58, of a bell crank lever, the remainingarm 59 of which, is pivoted at 60, to a boss 61, projecting from base19. Arm 58, is shown provided with a slot 62, and a pin 63, mounted onlever 50, completes the slotted connection before referred to.

Reference will next be made to instrumentalities operatively interposedbetween the master cam and lever 50, whereby an interdependent relationis established be tween said cam and said lever.

- What I will term a break-joint pawl, is shown in two parts and thepivoted or supporting part consists of a pawl. arm 64 which is pivotedat 65, to boss 61. A pawl part or portion is designated at 66 and isshown to be of U-shape, in cross section. Said pawl portion 66, isunited with the supporting portion 64, by a pivot 67, and the lower end68 overhangs the pivotal connection so that a break oint movement of theparts toward a straight or linear position, is limited to therelationship shownin Fig. 1. 69 of pawl section 66 partly laps the sidefaces of the cam 35 and rides on the periphery thereof, as clearlyshown. I preferably make the part 64 in theform of a bell crank, anarm70, thereof, forming a suitable lever- The cam end age'for connection ofone end of a spring 71,

the free end of which extends slidably through a lug 72, on pawl 66.This spring I is arranged and tensioned to urge the parts 5 66 and 6&toward and into the position shown in Fig. 1, but permits the parts tobuckle or break jointas shown in Fig. 2, for a purpose to be more fullydescribed later on. In actual practice,'a spring is not absolutelynecessary in order to maintain the pawl parts 66 and 64 in engagementwith the cam 35 although a spring tension makes the pawl action moreresponsive. Therefore, I have shown a tension spring 73, having itslower end connected to arm 70 to urge the pawl end 69 into engagementwith cam 35.

The pawl member 64, is provided with an opening 74:, into which projectsa lug 75, forming a. part of arm 59, thereby forming an operativeconnection between the breakjoint pawl and the detecting arm 50. Thus itwill be clear from Fig. 9, that as the breakjoint pawl is shifted to theright of its pivot 65, the bell crank arm 58 will be shifted out wardlyfrom base 19, thereby moving arm 50 in the same direction'andwithdrawing stud 53 slightly from the coin chute, and that a movement ofthe break-j oint pawl to the left of Fig. 1, or as viewed therein, thelever 50 would be allowed to move toward the base 19 and cause acorresponding entrance of stud 53 into the coin chute. The operation ofthis portion of the invention will be more fully described later on.

In order to make the construction clear, I have just described theseparate parts 64 and 66 of the break-joint pawl but hereafter, I willrefer to this feature as the break-joint pawl and will provide it with ageneric designation A.

Before enterlng into a description of the master cam 35, I will firstdescribe a check pawl, the function of which is to check the cam 35against retraction from an operatively advancing position or movement.

Said check pawl is indicated as a whole at 76 and is pivoted at 77 on aboss 78, which projects from base 19. Said pawl has a pawl arm 79 whichis provided with a ratchet pawl foot 80 which is flat or straight andwhich is adapted either toengage an arresting notch in the cam 35, to.be later described, or en gage ratchet tooth portions of said cam. Saidpawl has an arm 81, that is adapted to be spring actuated, and forconvenience, I employ spring 73, to which said arm 81 is connected. Thisspring 7 3 maintains said foot 80, in engagement with cam 35.

Said check pawl 76 performs additional functions which will next bedescribed in detail.

An arm 82 of said pawl is connected with an operating rod 83 whichextends downwardly between the cam 35 and base 19 and is connected atits lower end 84, to an arm 85,.as more clearly shown in Figs. 4 and 5.This arm 85 is mounted on a coin diverter shaft 86, journalled inbearings 87 and 88, formed on forked sections 21 and 20, respectively,of base 19. Mounted on said shaft 86, is an improved coin or entitydiverter which, as shown, consists of a U-shaped sheet of materialhaving a bight 89 and limbs 90, and said limbs 90 may be secured to saidshaft by means indicated at 91. Thus it will be seen that the top ofthis diverter is spaced some distance below the discharge end 10, of thecoin chute and the lower edges of the limbs extend slightly below theshaft 86, to which they are mounted. V

The function of this diverter is to divert genuine coins rearwardly intoa coin box, generally indicated at 92, and to divert slugs or unvendablecoins forwardly into asuitable return receptacle, which is generally'indicated at 93, and which is accessible to the purchaser while ofcourse the coin box 92 is inaccessible except to the service man for themachine. 7 V

A counter 94, is mounted on section 21,-and is provided with anactuating arm 95, the

latter being pivoted at 96, to a link 97, the

remaining end of which is jointly connected with arm 85, to the lowerendSt, of operating rod 83. Thus, the operating rod 83 functions toactuate the diverter and the counter, in a manner to be more fullydescribed in the subsequent description of theoperation.

I will next describe the structure and pur pose of the master cam.

Although a circular and rotary form of cam is not essential to myinvention, this form is herein shown mounted on cam shaft 36. Said cam35 is provided with what I will term an arresting notch which isindicated at 98, and which is a somewhat elongated and rectangular typeof notch having a terminal or arresting end 99, adapted to coact withthe break-joint arresting pawl, and a terminal or arresting end 100,which is adapted to coactwith the foot 80,- of the check pawl 79. Thisarresting notch is disposed radially inwardly from the balance of thecams periphery, as will .be clearly seen, and the purpose of which willbe later developed. The major peripheral portion of the cam 35, asindicated at '101, has the greatest diameter and is provided withratchet teeth adapted to coact with pawl 79, to prevent any retractivemovement of cam 35 i from the rotative movement necessary to complete avending operation. The vending movement of cam 35, is in a clockwisedirection, viewing Fig. 1. r

The terminal 102, of the ratchet portion 101, constitutes an operatinghill of the cam from which descends a declining vale 103, also ofoperating significance, and which terminates at the arresting end100, ofnotch 98. From the opposite end 99, of said notch extends a concentrichill 104 which merges into an inclining vale 105, the latter terminatingat the remaining operating hill 106, which is the opposite terminal ofthe ratchet portion ofthe cam 35.

Reference will next be made to an improved brake mechanism which retardsadvance of the cam during a vending ope ation of the latter and which isdesigned and constructed greatly to relieve the break-joint pawl ofstrain in arresting the master cam from a vending operation.

Referring to Figs. 10 and 11., a hub 10!, is rigidly mounted or keyed toshaft 36 and is provided with a braking arm 108 which may be formedintegral with said hub 10'? and a gear wheel 109, which latter is in onepiece with said hub. A braking lever 110, is pivoted at 111, to saidbase 19 and is provided with a minor braking surface 112 and a'majorbraking surface 113, with which said braking arm coacts. A 'spring114has one end anchored at- 115, to base 19, andthe remaining end connectedat 116, to the free end of said lever 110. When the parts are in thenormal starting position shown in Fig. 1, the braking arm 108 is in theposition shown in Fig. 10, which is an abutting relation to the arm 110,thereby affording one of the greatest moments of resistance to vendingadvance of shaft 36, even though the spring 114 is not under muchtension. However, the resistance increases as the end of arm 108 rideson arm 110, as shown in dotted lines, and the operation of which will bemore fully described later on. In addition to acting as a yieldingbrake, this device causes the vending mechanism automatically to returnto a starting or normal position after a spurious entity has beenrejected.

Before entering into a detailed description of the operation, it may nowbe informative to state specifically certain functions that the deviceis adapted to perform so that the latter will be clarified in the lightof the preceding description.

The throat device, shown in Fig. 12, will prevent entrance of entitiesthat are mutilated by being buckled or bent, and it will prevententrance of entities that are either too thick or of a too greatdiameter.

The magnet will cause discharge of what I term magnetic entities suchfor instance as slugs made of iron or steel, before such entities reachthe detector.

The arresting plate and detector will .per mit coins or slugs of a smalldiameter to im mediately pass through and be returned to the purchaser,without effecting any vending or other operation of the mechanism.Genuine coins of prescribed diameter that are worn too thin, will alsobe rejected, likewise slugs of the same character, and slugs that have acentral perforation will also be rejected' i I The operation will now bedescribed in detail.

Although not essential to the invention, the machine shown is designedfor operation with nickles. However, it is capable of being proportionedfor dimes, quarters or in fact any denomination of money, or rathercurrency.

If a dime should be inserted in the present machine, it could readilypass through the throat device 3, down the chute sections 7, 3 and 9,and by reason of the fact that in a starting or normal position therocking plate 22, is always in the Fig. 4, position, the dime would notbe arrested by the withdrawn studs 25, and the projected studs 23, arespaced far enough apart to permit a dime to pass through or betweenthem. Thus the dime would discharge at- 10, and as the diverter 90, isalways in the Fig. 4, position. when the mechanism is in a normal orstarting position, the dime would be diverted into the return receptacle93, which is accessible to thepurchaser. This would all occur before thepurchaser could operate the usual turn knob B, with which devices ofthis character are equipped. However, suppose the purchaser, after de'-,positing a dime, turned the knob B, in a clockwise direction with a viewof causing a vending operation, which is the only way it can be turnedby reason of the check pawl 79, engaging the arresting notch 98, then,and in that event, a movement would result which I will next describe. vv v The cam 35 would be turned from the Fig. 1 to the Fig. 2, position,and as nothing would be interposed between the detection stud 53 and theback wall of the coin chute, this stud 53 would be free. to enter thechute to the fullest extent under the act-ion of s'pring52. Suchmovement would (Fig. 9) cause arm 50 to move toward base-19 and lug 75would move the break-joint pawl A, to firmly engage the periphery of cam35 and'thereby cause the end 69 to enter notch 98, and as abutment 99engaged end 69, a further movement of the cam 35 would break thebreak-joint pawl into the Fig. 2, position thereby locking the sections64 and 66, and preventing further rotative movement of cam 35. The upperend of section 64, has a flattened portion 64 that engages the bight 66,of section 66, as clearly shown in Fig. 2. As this movement is beingeffected and arrested, arm 108 (Fig. 10) rides onto the abutment portion113, tensioning the spring 114 and thus resists such movement therebytaking much of what would otherwise be a strain subjection from thebreak-joint pawl. I As the knob is released, recoil of spring 114quickly restores the parts from the Fig. 2, to the Fig. 1, position,with the arms 108 and 110 in the full line postion in Fig; 10.

In this arrested movement of the mecharise, t e am tud. 39 vealahavemoved. out

of engagement with cam 42, and into the 2, position, thereby releasinglever l0 for movement by spring 43, into an upward position as far asslotted arm 4-9 would permit. This would cause the end 1-7, of lever 10,to slide to the outer end of slot 48, as shown. in Fig. 5, therebyrocking plate 22 from the Fig. 1 to the Fig. 5. position, wherein theupper studs 25 would be projected into the chute and the lower studswithdrawn. Should the purchaser deposit a dime and turn knob B beforethe dime had reacied point in its decent adjacent the plate 22, theabove operation would take place even if the studs 25 were projectedinto the coin chute thereby arresting the dime before the latter reachedplate 22. In the following restoring movement, above described, theplate 22 would be restored to the Fig. 1, position, thereby releasingthe dime for gravity passage between studs 23, and out through thedischarge end 10, as will now be clear.

Suppose a ferrous entity were deposited, would be attracted by themagnet poles l0 and shifted from its path down section 8, into dischargesection 11 and out through dischargeend 12, as shown in F 13, and wouldnever reach the detecting mechanism. The non-ferrous strip l7, wouldprevent the ferrous entity from freezing to the magnet poles 1 6.

Now it will be assumed that a slug had been inserted having a centralperfo 'ation as shown in 15. If this slug was of the same diameter as anickel, and of non-ferrous metal, it would descend in the coin chuteinto engagement with studs 23 and would be arrested thereby in aposition for detection. and the resulting rejectionwillnow be described.

Assuming that such perforated slug descended to the position shown inFig. 7, and was arrested by studs 23, it will be seen that theperforation would be centered with respect to the detection stud 53(Fig. 9). Thus, the operation would be much the same as was described inconnection with movement of the parts when a dime was inserted. Byturning the knob B clockwise, the breakoint pawl would ride down thevale 10.3 thereby ermitting spring 52 to move arm 50 toward liase 19 andcause detection stud 53 to enter the coin chute. As the opening in theslug would not arrest movement of stud 53, the break-joint pawl end 69would ride into notch 98 and engage terminal 99 and further clockwisemovement of cam would cause the pawl to break at its joint as shown inFig.2, and arrest further movement of the cam. I As the knob B wasreleased by the purchaser, the parts would be restored to the Fig. 1,'position, whereupon the plate 22 would be rockedto the same position.However, in movement of the parts to the Fig. 2, position, the plate;22' would be rocked to the Fig. 4, po ition, thereby releasing the slugjust" as soon as the stud 53'had been slightly with drawn, or, in someadjustments, and fact in most adjustments, the stud 53 would never enterthe coin chute far enough to project into the perforation in the slug.Thus, in the latter event, just as soon as the plate 22 was rocked tothe Fig. 4, position, the slug would be released and would be shifted bythe diverter 90, into the pocket 93. The stud 53 is, as heretoforeexplained, adjustable in arm in accordance with the extent to which itshould be projected into the coin chute.

I will next describe the operation which takes place when a nickel orentity of genuine character is inserted into the chute and a vendingoperation takes place.

When a genuine coin of prescribed denomination has been inserted intothe coin chute it will descend therein and be arrested by studs 23, inthe position shown in Figs. 4; and 7 Rotative movement of knob B in aclockwise direction will permit break-joint pawl, after riding over peak102, to descend vale 103, and on this movement, arm 50 will project stud53 into engagement with the arrested nickel thereby arresting furtherinward movement of arm 50. Of course, the parts are so timed that studs23 will not be withdrawn from the coin chute until stud 53 has engagedand held the nickel for a momentary period. l he interposition of thenickel between stud 53 and the back wall of the coin chute prevents arm50 from moving toward base 19 far enough to cause bell crank 59 to movethe break-joint pawl end 69, into said arresting notch 98. Therefore,instead of said end 69 entering said notch and abutting againstterminal99, thereof, and arresting movement of cam 35, as it does when aperforated slug or a dime or a nickle worn too thin, are inserted, the

said end 69 rides over said notch 98 and does not engage it. Thus,detection has been accomplished showing that the entity acted upon isthe right thickness, and hence, a vending operation must take place. Asend 69 passes over notch 98, it rides on operating hill 104, of cam 35and this causes a clockwise movement of'the break-joint pawl which,viewing Fig. 1, causes arm 50 to move outwardly away from base 19, andthereby released thedetected nickel for discharge from the coin chute.As the break-joint pawl has passed the arresting notch, there is nothingto prevent the knob B from being turned a full revolution to complete avending operation.

It will ofcourse be understood that before or when the parts havereached the Fig. 3, position, stud 39 will have released cam 42 andlever4.0 will have been elevated by spring 4-3, thereby tilting plate 22 intothe Fig. 5, position, thus to remain until stud 39 again engages cam 42,and lowers lever 40. The upward and downward thrust of the end 47, slot-18, of arm 49, causes rocking ,7

ment of plate 22 and the guide pins 28 and 31, l mit any verticalmovement thereof, as Wlll now be clear.

As the cam is turned, it will be'seen that check pawl 79, has riddenupwardly on vale ine coin into the coin box 92-. This downward movementof rod 83, also moves arm 95, of the counter, downwardly, which thusconstitutes one portion of actuation thereof. When the cam 35 isadvanced far enough so that the check pawl 79, rides inwardly on vale103,

then, rod 8-3 is lifted or moved upwardly and the counter is finallyadvanced to indicate that a. vending operation has been effected. As itrequires first a downward and then an upward movement of arm 95 toregister a counting advance, it will be clear that the counter is neverthus operated on a partial or arrested movementof cam 85.

Reverting to the combined braking" and returning means shown in F 10, itwill be clear that as the cam 35 is advanced and the check pawl 79 isriding on the ra chet portion, arm 108 will be riding on arm 110, in acontra-clockwise direction, viewing Fig. 10, and after the arm 108 hasbeen elevated out of contact with arm 110, the latter is instantlyreturned by spring 11% and the abutment 113 is brought .into a positionto yielding arrest the cam 35, which has now been returned to normal.

Thus it will be seen that the check pawl 79, is positively effective inpreventing retractive or contra-cloclrwise movement of the cam 35,viewing Fig. 1, and that the returning means yieldingly resistsclockwise movement of said cam 35 from a normal or starting position andreturns it to such position from a. relatively slight advance therefrom.

As heretofore stated, sprin 73 is connect-- ed at its opposite ends toyieldingly maintain pawl 79 and break-joint pawl A, in engagement withthe cam wheel 35, and one spring is capable of performing these twofunctions, it is thus employed. However, spring 7 3 is of such lightertension than spring 52 as to make the latter dominant and primary.

It is believed that the device of this invention will be fullyunderstood from the foregoing description and while I have herein shownone specific form of the invention, I do notwish to be limited theretoexcept for such limitations as the claims may import.

I claim 1. In a coin controlled mechanism, a coin chute adapted toreceive a plurality of superimposed genuine ancl spurious entities, a

rocking entity controlling frame having a lower set of studs forarresting an entity in a detection position and an upper set of studsfor arresting the remaining entities from entering a. detectionposition, adetection device movable into a detection position withrespect to a correspondingly positioned entity to determine thecharacterof the latter, and means for rocking said frame to alternatelydispose said sets of studs in arresting positions in said chute. p

2. In a coin controlled mechanism, a'coin chute adapted to receiveentities, a rocking entity controlling plate having sets of entityarresting studs, one set of studs being spaced apart to arrest an entityof a diameter less than the prescribed diameter and the remaining setbeing spaced apart to permit passage of such smaller diameter entity andclose enough to arrest an entity of prescribed diameter, means forrocking said plate to dispose either set of studs in an arrestingposition'in said chute, and detection means operating against anarrested entity of prescribed diameter.

3. In a coin controlled mechanism, a coin chute for receiving'entities,an entity controlling device' for temporarily arresting an entity inadetection position in'said chute, detectio-nmea-ns movable into saidchute a predetermined distance into momentary engagement with an entityof prescribed thickness or moving into said chute'butnotengaging aperforated or too thin entity, and

means for actuating said device to release the arrested entity prior torelease of a genume entity by sa d ClQVlCB toprevent a vend ingoperation except when a coin of normal thic'kness is deposited in thechute.

4. In a coin controlled mechanism, a coin chute for entities, afloating, rocking plate having upper and lower sets of entity arrestingstuds adapted alternately to be projected into said chute" as saidpl'ateis rocked, tulcrum guide'pins for giiidingsaid plate inits rockingmovement, a spring normally acting to move said plate toward said chute,a slotted arm fixed to said plate and'projecting lat erally of the planethereof, a lever s'lidable in said slotted arm and being actuated toimpart thrusts to said platein different directions in the plane of'saidplate to rock the latter into different entity arresting positions, andmeans for detecting an entity while the latter arrested by said lowerset of studs.

5. In a coin'controlled mechanism, a coin chute adaptedto receive anentity for-thickness detection thereof preliminary to a vending ornon-vending operation, means for arresting an entity in a detectionposition in saidchute, a spring actuated detector arm having a detectorst ud movable into said chute for engagement with an entity of theprescribed thickness, 'a' master cam having an arresting notch, abreak-joint pawl actuated by said armto engage said pawl with said cam"and shifting said pawl into said notch to break said pawl andcausethelatter to arrest vending movement of said cam when a perforatedor too thin entity permits said stud to enter too far into said chute,or holding said pawl free from said notch on engagement of said studwith a normal thickness entity thereby permitting vending movement ofsaid cam.

6. In a coin controlled mechanism, a coin chute adapted to receiveentities, means for arresting an entity in said chute in a detectionposition, a spring actuated detection arm provided with a detection studadapted to enter said chute, a master cam provided with a pawl arrestingnotch, a pawl operatively connected with and urged by said arm intoengagement with said cam, said cam having a vale permitting movement ofsaid stud into said chute for engagement with a normal thickness entityto prevent said pawl from engaging said notch or permitting furthermovementof said stud toward a too thin or perforated arresting entity topermit said pawl to engage said notch and prevent a vending operation,and means for automatically restoring the parts to a normal positionfrom a partial or non-vending position.

7. In a coin controlled mechanism, a counter, a coin chute for entitiesprovided with adischarge end, entity arresting and detecting mechanismfor said chute, a. diverter below said discharge end for divertingspurious entities in one direction and genuine entities in anotherdirection,'a check pawl for operating said counter and diverter, and amaster cam having a series of ratchet teeth for engagement with saidcheckpawl to prevent retractive movement of said cam, and said camhaving hill and vale portions for actuating said check pawl to operatesaid counterand diverter.

8. Ina coin controlled mechanism, a coin chute adapted to receiveentities, means for arresting an entity in said chute for detectionpurposes, means for detecting spurious from genuine entities while theentity is arrested in said chute, a pawl connected with said means tooperate the latter or be operated thereby, a master cam engaging saidpawl, said cam having a portion permitting operation of said pawl bysaid means responsive to a spurious entity for arresting a vendingoperation or operating said pawl responsive to a genuine entity topermit a vending operation, and said cam having portions for causingsaid pawl to operate said means to retract the latter.

9. In a coin controlled mechanism, a coin chute adapted to receiveentities, means for arresting an entity in said chute for detectionpurposes and then releasing such entity, means for detecting spuriousfrom genuine entities while the entity is arrested in said chute, adevice connected with said means to operate the latter or be operatedthereby, and an element engaging said device and having aportionpermitting operation of said device by said means responsive to aspurious entity for arresting a vending operation or operating saiddevice responsive to a genuine entity to permit a vend ng operatlon.-
